Models of Ni- and Co-ion occupation in LiNiCoPOorthophosphate and its magnetic structure.

The neutron diffraction, magnetic and heat capacity measurements have been carried out to study the polycrystalline sample LiNiCoPOprepared by the glycerol-nitrate synthesis method. Models of Ni- and Co-ion occupation the 4octahedral position in a crystal structure LiNiCoPOare calculated for a paramagnetic state. The best model is the Ni- and Co-ions occupy the 4site inpatent space-group in sequence Ni-Co-Ni-Co or Co-Ni-Co-Ni.
